Keras seems to hang after call to fit_generator
问题 I am trying to fit the Keras implementation of the SqueezeDet model to a new dataset. After making the appropriate changes to my config file, I tried to run the train script, but it seems to hang after the call to fit_generator() . As I get the following output: /anaconda/envs/py35/lib/python3.5/site-packages/h5py/__init__.py:36: FutureWarning: Conversion of the second argument of issubdtype from `float` to `np.floating` is deprecated. In future, it will be treated as `np.float64 == np.dtype
